Carefully enter all verification codes.
〈 Registration Steps 〉

▶Which Credit Cards Cannot Be Used with Babycal?
Please prepare a valid credit card.
〈BabyCalTroubleshootingGuide〉
✕ Debit cards linked directly to a bank account
✕ Prepaid cards
✕ Some cards that do not support 3D Secure 2.0, including certain UnionPay cards
✕ Expired cards
✕ Cards that have exceeded their credit limit
After entering your card information, 3D Secure 2.0 authentication will be performed to verify your card.
![[Member Registration] Please tell me about the credit card required for registration.](https://babycal-jre.com/lp/wp-content/uploads/2026/07/ee7450caacd46de0477e7d56f0471a39.png)
▶Tips for Successful Card Registration
Please ensure that:
☑ Your internet connection is stable.
☑ You do not close the browser or app during authentication.
☑ Authentication codes are entered correctly.
☑ Your credit card is valid and available for use.
▶Unsupported Cards
３．Identity Verification (3D Secure)
▶What Is 3D Secure?
3D Secure 2.0 is an identity verification service provided by major international card brands including:
・Visa
・Mastercard
・JCB
・American Express
・Diners Club
It helps prevent unauthorized use of credit cards during online transactions.
Depending on your card issuer’s risk assessment, you may be asked to verify your identity using a one-time password or another authentication method.
When registering or updating your credit card with BabyCal, you may be asked to complete 3D Secure authentication.
Please follow the instructions displayed by your card issuer.
〈 Important Notes 〉
3D Secure is provided by your card issuer, not BabyCal.
Authentication methods and error messages vary by card issuer.
Please contact your card issuer if you have questions about authentication or receive an error.
Even after successful authentication, payment authorization may still be declined depending on your card’s status.
If an error continues, please try registering another credit card.
▶Why Is 3D Secure Verification Required for My Credit Card?
3D Secure is a security feature designed to protect your credit card from unauthorized use.
Even if your card information, such as your card number, is compromised, 3D Secure helps prevent anyone other than the cardholder from using the card without permission.
To provide a safe and secure rental experience, BabyCal may require 3D Secure authentication when you register or update your credit card.
Whether authentication is required is determined by your card issuer.
Authentication is not requested for every customer or every transaction.
We apologize for the extra step during your first registration.
Thank you for your understanding and cooperation in helping us keep your account secure.
４. If You Cannot Complete Credit Card Registration or 3D Secure Authentication
▶Common Reasons Why Credit Card Registration or Verification May Fail
If you are unable to register your credit card or complete 3D Secure authentication, please check the following before trying again.
・Make sure you have a stable internet connection.
（Do not close your browser or the app while the authentication process is in progress.）
・Confirm that your credit card is valid and available for use.
・Make sure you entered the authentication code correctly.
・Try another 3D Secure 2.0-compatible credit card.
▶Unsupported Credit Cards
【 Important 】
Even if a card has a card number, expiration date, security code, and card brand logo, the following cards cannot be used:、
× Debit cards (linked directly to a bank account)
× Prepaid cards (cards that require funds to be loaded in advance)
Please register a credit card as your payment method.
Because 3D Secure authentication is managed by your card issuer, the authentication process and error messages differ by issuer.
For this reason, BabyCal may not be able to determine the exact cause of an authentication error.
If the problem persists, please contact your card issuer for assistance.
▶Checklist if Card Registration or 3D Secure Authentication Fails
▶Things to Check First If You Cannot Register Your Credit Card or Complete Verification
Please check the following items before trying again.
□ Are you using a stable internet connection?
（Wi-Fi or mobile data interruptions may prevent authentication from completing.）
□ Did you keep the browser or app open throughout the authentication process?
（Closing the authentication screen or leaving it before completion may cause the process to fail.）
□ Did you enter your card number, expiration date, and security code correctly?
□ Did you enter the one-time password (OTP) or other authentication code correctly?
□ Has your credit card expired?
□ Has your card been suspended or exceeded its credit limit?
□ Is your card compatible with 3D Secure 2.0?
（Some cards, including UnionPay cards, may not support 3D Secure 2.0.）
□ Are you using a debit card or prepaid card?
（Debit cards and prepaid cards are not accepted.）
▶Last resort if your membership registration fails
If you still cannot complete registration or authentication after checking the items above, we sincerely apologize for the inconvenience.
Please try registering using the other version of BabyCal.
BabyCal offers both a Web Version and an App Version.
Each version has its own separate membership registration system.
Even if you use the same email address and password, your account is not shared between the Web Version and the App Version.
- If registration failed on the Web Version, please try the App Version.
- If registration failed on the App Version, please try the Web Version.
We apologize for the inconvenience and appreciate your cooperation.

10. Troubleshooting During Your Rental
▶How to Remove a Stroller or Wheelchair from an Unmanned Rental Station.
- Press “Member Authentication” on the rental machine.
- Scan the QR code displayed in your reservation.
- Select the number shown on the screen.
- Press “Confirm.”
The indicator light will turn on, allowing you to remove the IC key from the corresponding slot and take the stroller or wheelchair.
▶What to Check If the Stroller Wheels Won’t Move
Please check whether the wheels are locked.
【 Rear wheels 】
The rear-wheel brake is engaged when the brake lever is pushed downward.
This brake prevents the stroller from moving unintentionally when parked, especially on slopes.
If the rear wheels are locked while you are trying to use the stroller, lift the brake lever upward to release the brake.
【 Front wheels 】
The front wheel lock should normally remain unlocked (lever down).
If the front wheel lock is engaged, the stroller will not turn easily and may only move straight ahead.
If the stroller is difficult to steer, please check that the front wheel lock has been released.
If the wheels still do not move after confirming they are unlocked, please contact the Babycal Customer Support Center.
▶︎How to Recline the Stroller Seat
To recline the seat, pull the recline strap located behind the seat.
To return the seat to the upright position, make sure no weight is pressing against the backrest, then pull the end of the recline strap.
Please note:
Type B strollers (for children approximately 7 months to 4 years old (48 months)) cannot recline completely flat like Type A strollers (for children approximately 1 month to 4 years old (48 months)).
Please use equipment that is appropriate for your child’s age and weight.
▶I Forgot My Phone and Cannot Display My QR Code
You must display your QR code to complete the rental procedure.
Please make sure you bring the smartphone or tablet that displays your QR code when visiting the rental location.
▶Can the User Be Different from the Person Who Made the Reservation?
No.
The reservation must be made by the person who will use the equipment.
For wheelchair rentals, the reservation should be made by the person accompanying the wheelchair user (caregiver or attendant).
▶What Should I Do If I Damage the Rented Equipment, Such as a Stroller or Wheelchair?
Continuing to use damaged equipment may result in unexpected injury or accidents.
Please stop using the equipment immediately and contact the Babycal Customer Support Center.
▶What Should I Do If I Accidentally Get the Stroller or Wheelchair Dirty?
Please wipe off any dirt and return the equipment in a clean condition.
If the dirt cannot be removed, please contact the Babycal Customer Support Center.
▶I Left Something in the Stroller or Wheelchair After Returning It
Your lost item may have been kept at the rental location.
Please contact the facility where you rented the equipment directly.
▶Unsafe Uses to Avoid for Your Safety
Please follow these safety precautions to help prevent accidents, injuries, and damage to the equipment.
⚠️ Use equipment that is appropriate for your child’s age and weight.
⚠️ Never leave your child unattended while seated in the stroller.
⚠️ keep your child’s seatbelt fastened at all times while using the stroller.
⚠️ Do not attempt to force the stroller or wheelchair over steps, stairs, or other large obstacles.
⚠️ Always apply the rear wheel brake before placing your child in or taking your child out of the stroller.
⚠️ Never hang heavy things on the handle; risk of tipping over.
Doing so may cause the equipment to become unstable, tip over, or be damaged because every stroller and wheelchair has a maximum weight limit.
